Umklamo wefomula we-MCA kanye ne-Aluminium Hypophosphite (AHP) ku-Separator Coating ukuze kuvinjwe ilangabi

Ngokusekelwe ezidingweni zomsebenzisi ezithile zezingubo zokuhlukanisa ezivimbela umlilo, iziciI-Melamine Cyanurate (MCA)futhiI-Aluminium Hypophosphite (AHP)zihlaziywa kanje:

1. Ukuhambisana nezinhlelo ze-Slurry

• I-MCA:
• Izinhlelo zamanzi:Kudinga ukuguqulwa kwendawo (isb., ama-silane coupling agents noma ama-surfactants) ukuze kuthuthukiswe ukuhlakazeka; ngaphandle kwalokho, kungase kube nokuhlangana.
• Izinhlelo ze-NMP:Kungabonisa ukuvuvukala okuncane ezincibilikisini eziphansi (kunconywa: hlola izinga lokuvuvukala ngemva kokucwiliswa kwezinsuku eziyi-7).
• I-AHP:
• Izinhlelo zamanzi:Ukusabalala okuhle, kodwa i-pH kumele ilawulwe (izimo ze-asidi zingabangela i-hydrolysis).
• Izinhlelo ze-NMP:Ukuqina kwamakhemikhali aphezulu kanye nengozi encane yokuvuvukala.
  Isiphetho:I-AHP ikhombisa ukuhambisana okungcono, kuyilapho i-MCA idinga ukuguqulwa.

2. Usayizi Wezinhlayiyana kanye Nokuzivumelanisa Nenqubo Yokumboza

• I-MCA:
• I-D50 yokuqala: ~1–2 μm; idinga ukugaya (isb., ukugaya isihlabathi) ukuze kuncishiswe usayizi wezinhlayiya, kodwa kungalimaza isakhiwo sayo esinezingqimba, kuthinte ukusebenza kahle okuvimbela ilangabi.
• Ukufana ngemva kokugaya kumele kuqinisekiswe (ukubonwa kwe-SEM).
• I-AHP:
• I-D50 yokuqala: Ngokuvamile ≤5 μm; ukugaya ku-D50 0.5 μm/D90 1 μm kungenzeka (ukugaya ngokweqile kungabangela ukujiya kwe-slurry viscosity).
  Isiphetho:I-MCA inokuguquguquka okungcono kosayizi wezinhlayiya kanye nengozi ephansi yenqubo.

3. Ukumelana Nokunamathela Nokuguguleka

• I-MCA:
• I-polarity ephansi iholela ekunamatheleni okungekuhle kwamafilimu okuhlukanisa i-PE/PP; kudinga ama-binder asekelwe ku-acrylic angu-5–10% (isib. i-PVDF-HFP).
• I-coefficient ephezulu yokungqubuzana ingadinga ukwengeza i-0.5–1% nano-SiO₂ ukuze kuthuthukiswe ukumelana nokuguguleka.
• I-AHP:
• Amaqembu e-hydroxyl angaphezulu akha izibopho ze-hydrogen ne-separator, okuthuthukisa ukunamathela, kodwa kusadingeka ama-polyurethane binders angu-3–5%.
• Ubulukhuni obuphezulu (Mohs ~3) bungabangela ukuchitheka kwezinhlayiya ezincane ngaphansi kokungqubuzana isikhathi eside (kudinga ukuhlolwa okujikelezayo).
  Isiphetho:I-AHP inikeza ukusebenza okungcono kakhulu kodwa idinga ukulungiswa kwe-binder.

4. Izakhiwo Zokuzinza Kokushisa Nokubola

• I-MCA:
• Izinga lokushisa lokubola: 260–310°C; ayikwazi ukukhiqiza igesi ku-120–150°C, okungenzeka yehluleke ukucindezela ukugeleza kokushisa.
• I-AHP:
• Izinga lokushisa lokubola: 280–310°C, futhi alanele ukukhiqizwa kwegesi emazingeni okushisa aphansi.
  Inkinga Eyinhloko:Zombili ziyabola ngaphezu kwebanga eliqondiwe (120–150°C).Izixazululo:
• Faka ama-synergists okushisa okuphansi (isb., i-phosphorus ebomvu efakwe ema-microcapsulated, ibanga lokubola: 150–200°C) noma i-modified ammonium polyphosphate (i-APP, embozwe ukuze kulungiswe ukubola kube yi-140–180°C).
• Yakha i-Inhlanganisela ye-MCA/APP (isilinganiso esingu-6:4)ukusebenzisa ukukhiqizwa kwegesi okuphansi kwe-APP + ukuvinjelwa komlilo wesigaba segesi se-MCA.

5. Ukumelana ne-Electrochemical kanye nokugqwala

• I-MCA:
• I-melamine engenamakhemikhali ngogesi, kodwa esalayo (ubumsulwa obudingekayo ≥99.5%) ingase ibangele ukubola kwe-electrolyte.
• I-AHP:
• Ukungcola okune-asidi (isb., i-H₃PO₂) kumele kuncishiswe (ukuhlolwa kwe-ICP: ama-ion ensimbi ≤10 ppm) ukuze kugwenywe ukusheshisa i-LiPF₆ hydrolysis.
  Isiphetho:Zombili zidinga ukuhlanzeka okuphezulu (≥99%), kodwa i-MCA kulula ukuyihlanza.

Isiphakamiso Sesixazululo Esiphelele

1. Ukukhetha Okuyinhloko Okubambezela Umlilo:

• Okuthandwayo:I-AHP (ukuhlakazeka/ukunamathela okulinganiselayo) + i-synergist yokushisa okuphansi (isb., i-phosphorus ebomvu engu-5% encane efakwe emaphaketheni).
• Okunye:I-MCA eguquliwe (efakwe i-carboxyl ukuze kusakazwe amanzi) + i-APP synergist.

1. Ukuthuthukisa Inqubo:

• Ifomula yodaka:I-AHP (90%) + i-polyurethane binder (7%) + i-wetting agent (BYK-346, 0.5%) + i-defoamer (2%).
• Amapharamitha okugaya:Isigayo sesihlabathi esinobuhlalu be-ZrO₂ obungu-0.3 mm, 2000 rpm, amahora ama-2 (target D90 ≤1 μm).

1. Ukuhlolwa Kokuqinisekisa:

• Ukubola kokushisa:I-TGA (ukwehlisa isisindo <1% ku-120°C/2h; ukuphuma kwegesi ku-150°C/30min nge-GC-MS).
• Ukuzinza kwe-electrochemical:Ukubonwa kwe-SEM ngemva kokucwiliswa kwezinsuku ezingu-30 ku-1M LiPF₆ EC/DMC ku-60°C.

Isincomo Sokugcina

I-MCA noma i-AHP zodwa azihlangabezani nazo zonke izidingo.uhlelo oluhlanganisiwekuyelulekwa:

• I-AHP (i-matrix)+i-phosphorus ebomvu efakwe emaphaketheni amancane (ijeneretha yegesi ephansi lokushisa)+i-nano-SiO₂(ukumelana nokuguguleka).
• Hlanganisa ne-resin yamanzi enamathelayo ephezulu (isb., i-acrylic-epoxy composite emulsion) bese ulungisa ukuguqulwa kwendawo ukuze kube nobukhulu bezinhlayiya/ukuqina kokuhlakazeka.
  Ukuhlolwa okuqhubekayokuyadingeka ukuqinisekisa ukusebenzisana kwe-thermal-electrochemical.
